Abstract :
Currently, the voltages of power supply on electric vehicle are far higher than the level that people can endure. How to resolve the insulation failure detection in all kinds of electric vehicle have not been concluded. Aiming at the high voltage safety of electric vehicle, a solution based on FPGA is introduced in this paper. It first gives the analysis of people getting electric shock in EV, and then presents the principle of the detecting method and its realization. In the solution, a kind of filter circuit is provided for the power supply on electric vehicle while the device of FPGA is used to count the insulated resistance of power supply and control the switches. The result of experiment indicates that, applied on electric vehicle, this solution takes effect on the detection and protection for the creepage of power supply and personpsilas getting an electric shock.
